OC Japan Fair 2026 — Fall Edition

You found this. Be the first one here.

Somewhere between the taiko drums shaking the floor and the takoyaki line that hasn't moved in ten minutes, you'll realize you've been here for four hours and haven't checked your phone once.

OC Japan Fair takes over the OC Fair & Event Center every fall with 130+ booths, an estimated 45,000 visitors across three days, and a schedule that runs from J-pop performances and cosplay shows to kimono try-ons and Japanese calligraphy workshops. It is not a food fair with cultural garnish — it's a cultural fair with an absurd amount of food. The ramen vendors alone could fill a separate event.

The K-PLAY! crossover means the cosplay crowd, the K-pop crowd, and the otaku crowd all land in the same space at the same time, which creates the kind of energy you don't plan. You just show up and it finds you.

October 16–18, 2026. Friday 4–10 PM, Saturday 12–10 PM, Sunday 11 AM–7 PM. OC Fair & Event Center, 88 Fair Dr, Costa Mesa 92626. Tickets $14–$20.
